"Adobe first launched Creative Suite 1 back in 2003, and now, ten years and six versions later, the company is taking a left turn: Adobe is abandoning its Creative Suite entirely to focus efforts on Creative Cloud."

How is making the Adobe suite cheaper and more accessible to all users going to help GIMP?

Because I dare say the vast majority of Photoshop 'users' today are running a pirated version of Photoshop.

For amateurs/hobbyists who only use a very small subset of the features Photoshop offers, they can likely get those features from free applications.

If they can no longer pirate Photoshop a huge amount of these users will not find Photoshop worth the asking price and will turn elsewhere, possibly to Gimp.

Photoshop will remain the de facto choice amongst professionals, as it should be in my opinion given that it is the best software of it's type and have no real rival either from other commercial offerings nor from open source.
